Doing the IndoorLoiter project based on this project https://ardupilot.org/copter/docs/common-pozyx.html
Now I’m facing issues due the precision of the pozyx anchor ranging system. The Z-axis has a 20cm off accuracy which is causing Altitude “instability”. I want to maximise the stability, so I can resume my project and plan missions indoors. Accuracy is something where I’m looking for in this project, because the drone needs to map it’s course, so it can be flown again by the drone pilot. I did some research and found some Lidars that are being supported by ArduPilot/MP. My budget is max. around €50,00 for the Lidar. So this bring me to the following Lidars:
TFmini Plus https://drones.altigator.com/tfmini-plus-rangefinder-12m-p-42669.html?zenid=48j4v912cbkiih15fb9qjn32i5 --> how well does it perform?
XL-MaxSonar-EZ https://www.maxbotix.com/product-category/xl-maxsonar-ez-products --> Lots of questionmarks on the reliablity of their collection and which one is actually suited.
ST VL53L0X / VL53L1X Lidar https://ardupilot.org/copter/docs/common-vl53l0x-lidar.html --> Cheap, but propably not reliable.
TeraRanger Evo Mini https://www.terabee.com/shop/lidar-tof-range-finders/teraranger-evo-mini/ -->I’m wondering if this one has the same support as the TeraRanger One?
Does a combination with an optical flow sensor makes much difference?
Anyone here tested one of these and is very satiesfied with its performance?
